Morrissey and three others were injured at 5:50 p.m. July 16, when Morrissey’s Ford Explorer, which was traveling east, crossed the double-yellow line on Centre Street near Milton Academy and collided with two vehicles traveling in the opposite, westbound lane.

A fourth vehicle behind Morrissey’s swerved off the road to avoid the crash.

Milton police cited Morrissey for a marked-lane violation. He paid a $100 fine at the Quincy court shortly after the magistrate hearing was over.

Morrissey, 58, released his medical, traffic and cellphone records by email Monday afternoon. He said he did so “in the interest of public disclosure.”

Morrissey told The Patriot Ledger that he didn’t ask a specially appointed Worcester District Court clerk magistrate to close the hearing because “show cause” hearings are “presumptively private” under district court rules.

He said it was up to Clerk Magistrate Michael Prosser to open the hearing. Reporters from The Patriot Ledger and Boston news media outlets sent a written request to Prosser after the hearing was under way, but he kept it closed.

Prosser couldn’t be reached for comment after the hearing as to why why he kept it closed.

The state trial court’s administrative justice chose an outside magistrate for Morrissey’s hearing because he and his prosecutors are in daily contact with the Quincy court.

Morrissey didn’t take media questions after the hearing. Outside the courthouse he said the medical records and other evidence he and his attorney, Anthony Campo, presented to Prosser showed that the accident was caused by what he called an “isolated fainting episode.”

He said he was dehydrated and fatigued that day, “one of the hottest days of the year.”

A vasovagal syncope is a sudden drop in heart rate and blood pressure, which reduces blood flow to the brain. It’s usually medically harmless and needs no treatment.

Outside court he also said – as Milton police had previously confirmed – that speed and cellphone use weren’t factors. Morrissey also requested a blood-alcohol test at the hospital to confirm that drinking hadn’t played a part in the crash either.

Morrissey said he’s “extremely grateful” that none of the others were seriously injured.

The State Police accident reconstruction report said Morrissey’s 2011 Explorer crossed the center yellow lines on Centre Street at 5:47 p.m., one minute after Verizon cellphone records indicate that Morrissey placed a call. (In the records he released, Morrissey notes “pizza” on the 5:46 p.m. call.)

The report said the DA was traveling 29 mph in a 30 mph zone, and that he was wearing his seat belt. The Explorer sideswiped a 2013 Toyota Highlander heading west on Centre Street, then struck a Ford F150 pickup truck head-on.

The Explorer spun before coming to a stop. The driver of a 2006 Toyota Tacoma behind Morrissey’s Explorer swerved onto the shoulder of the road to avoid the crash. His truck came to rest on a low stone wall.
